This may not be Dan’s take, but for me, this is a unique way to approach the “Law/Gospel” Issue. These are Jesus’ Kingdom ethics. It’s his amplification of the law, and his picture of what it means to follow him as King.
What’s needed? The cross. The Good News that for all of us who fall short of all of these all the time, there is a place of forgiveness, and a way to live for Jesus even if we can’t follow him perfectly or even consistently.
